In this section we will review and expand upon material you have been taught about in grades 9 and 10.
Metallic elements and non-metallic elements are involved in chemical reactions. When a metal combines with another metal, a chemical reaction does not take place but rather an alloy is created (an alloy is a solution of two metals). The properties of the alloy differ from those of the individual metals. Unfortunately, the theoretical background required for you to understand the model that explains the behaviour of alloys is beyond the scope of the course.
When a metal combines with a non-metal, the resulting reaction produces what is referred to as an ionic compound. We will explore the model that explains the behaviour of such substances. When a non-metal combines with a non-metal, the reaction produces a compound that is often referred to as a covalent compound. Because the behaviour of a covalent compound differs from that of an ionic compound, covalent compounds have a different model that accounts for its properties.
